2.0 Course Objectives CE405 is an introductory course in the design of steel structures. This course is recommended for seniors in the civil engineering program at MSU who are interested in learning the design of steel structures. The objectives of this course are: 1. To learn the behavior and design of structural steel components, for example, members and connections in two - dimensional (2D) truss and frame structures. 2. To gain an educational and comprehensive experience in the design of simple steel structures.
3.0 Course Materials and References 1. The course will follow the contents of the book: Segui, W.T. (1999). LRFD Steel Design. 2nd Edition, Brooks/Cole Publishing Company, Pacific Grove, California. 2. Steel structures will be designed according to: AISC (1999). Load and Resistance Factor Design Specification for Structural Steel Buildings, American Institute of Steel Construction, Chicago, IL. 3. Specific structural steel components will be selected using:

AISC (2001). Manual of Steel Construction – Load and Resistance Factor Design, Third Edition, American Institute of Steel Construction, Chicago, IL. 4.

4.0 Course Framework 1. CE 405 will consist of 15 weeks of lectures (including holidays and breaks). 2. Students will be assigned homeworks, exams, and a group design project. 3. The final grades will be based on the homeworks, exams, and design project as follows: • Homework = 15 % • Exam 1 = 20% • Exam 2 = 20% • Final Exam = 30% • Design Project = 15% 4. The final grades will be assigned on a straight scale, with some adjustment for the level of difficulty of the exams and overall class performance. If no adjustments are required then the final grades will be assigned as follows: Score ≥ 90 ≡ 4.0 85 ≤ Score < 90 ≡ 3.5 80 ≤ Score < 85 ≡ 3.0 75 ≤ Score < 80 ≡ 2.5 Score ≤ 60 ≡ 0.0
70 ≤ Score < 75 ≡ 2.0
60 ≤ Score < 65 ≡ 1.0
5.0 Course Policies 1. Attendance policy - Students are expected to attend all the lectures. They are also expected to adequately perform all the work assigned by the instructor. 2. Tardy policy - All the assigned work must be submitted by the due date and time. Submissions that are 0 - 24 hours late will be penalized for 25% of the grade. Submissions that are 24 - 48 hours late will be penalized for 50% of the grade. After 48 hours, submissions will neither be accepted nor graded. Exceptions can be made for students with emergencies or special circumstances.

3. Make-up policy - Students are expected to take the exams on the assigned dates and times. Make-up exams may be arranged for students with emergencies or special circumstances. 4. Quality of Submissions - Students are encouraged to submit their work on engineering paper or clean white paper. Please explain and show all your calculations. Include appropriate references to the AISC specifications and final drawings of designed structures.
6.0 Relevant University Policies and Procedures 1. Academic Honesty: Article 2.3.3 of the Academic Freedom Report states that "the student shares with the faculty the responsibility for maintaining the integrity of scholarship, grades, and professional standards." In addition, the Dept. of Civil and Environmental Engineering at MSU adheres to the policies on academic honesty as specified in General Student Regulations 1.0, Protection of Scholarship and Grades, and in the all-University Policy on Integrity of Scholarship and Grades, which are included in Spartan Life; Student Handbook and Resource Guide. Students who plagiarize may receive a 0.0 on the assignment or fail the course. 2. The last day to drop this course with a 100 percent refund and no grade reported is Thursday 09/14/2003. The last day to drop this course with no refund and no grade reported is Tuesday 10/14/2002. You should immediately make a copy of your amended schedule to verify you have dropped this course. 3. Religious Observance: If you wish to be absent from class to observe a religious holiday, make arrangements in advance with the instructor. 4. Missing Class to Participate in a Required Activity: To be excused from this class to participate in a required activity for another course or a university-sanctioned event, you must provide the instructor with adequate advanced notice and a written authorization from the faculty member of the other course or from a university administrator 5. Commercialized Lecture Notes: Commercialization of lecture notes and university-provided course materials is not permitted in this course.
